We are all high functioning until we aren’t.
This makes sense a lot of sense the way you put this. I guess my definition of HFA in my H's case was that he was functioning at work because he would quit drinking early enough in the morning so he'd be sober for work. Once he came home and started drinking again he stopped being very functional in a hurry. He was functional away from home up until he quit drinking and at that point things were really bad at home but he had not gone to work drunk (he didn't really do much away from home outside of work )
He was never one to hit the bars to go drink luckily because had that been the case I'm sure he would've ended up with a DUI at some point
